AUTOMATIC STOCK-WATERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 754,848, dated March 15, 1904.

Application filed June 11, 1903.

zen of the United States, residing at Beatrice,

in the county of Gage and State of Nebraska, have invented a new and useful Automatic Stock-Watering Machine, of which the following is a specification.

The invention relates to an automaticstockwatering machine.

The object of the present invention is to improve the construction of stock-watering machines and to provide a simple and comparatively inexpensive apparatus adapted to be operated by an animal and capable of automatically drawing a quantity of water and of delivering the same to the animal.

A further object of the invention is to provide an apparatus of this character in which the wateringtrough will a be automatically emptied after an animal is through drinking, whereby the apparatus is prevented from becoming frozen and inoperative in cold weather.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood.

that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figurel is aside elevation of a stock-watering apparatus constructed in accordance with this invention. Fig. 2 is a similar view, partly in section, of'the opposite side of the apparatus. Fig. 3 is a perspective view of the valve-casing and the valve-actuating mechanism. Fig. 4c is a vertical sectional view illustrating the construction of the valve mechanism and the valved bucket. Fig. 5 is a transverse sectional view illustrating the manner of mounting the drinking trough. Fig. 6 is a longitudinal sectional view of the same. Fig. 7 is a detail view of the check-valve.

manner of connecting the depending arm with the same. Fig. 9 is an enlarged sectional view illustrating the manner of mounting the adjustable inclined trip.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a vertical pipe or tube composed of sections and forming a valve-casing. One of the sections is provided with a valveseat 2, and it has suitable guides 3 and A for the reception of the vertically-movable valvestem 5, which carries a valve 6, arranged to close against the seat 2. The valve-seat is at the lower end of the section of the pipe or tubing, and the pressure of the water assists in holding the valve to its seat. The lower section 7, which may be connected with a water-main or any suitable source of supply, is preferably provided with a check-valve, as illustrated in Fig. 7 of the accompanyingdrawings. The checkvalve 8, which is arranged in a suitable section or casing 9, closes against and is located above a suitable seat, and it is adapted to prevent any back pressure. The check-valve is provided with arms or stems l0 and 11, arranged in perforations of braces 12 and 13, which form guides and supports for the check-valve. The section or casing 9 is provided with an. interiorly arranged tubular portion 1a, centrally connected with the section or casing and forming an upper valve-seat and having an interiorly-threaded lower end for the reception of a strainer or'screen 15 for catching sand and dirt. The braces or guides 12 and 13 are connected with the upper portion of the inteterior tubular portion 14. The check-valve may be omitted, if desired.

The valve-stem 5 extends through a central opening or perforation of a cap 16, formed integral with a top cross-piece 17 and interiorly threaded to screw on the upper end of the pipe or tube 1; but the screw-threads may be omitted and any other formof connection may be provided. The track or tube 1 is supported by an approximately rectangular frame 18, supported by corner-posts 19, preferably arranged at a slight inclination, as shown in Figs. 1 and 2. The rectangular frame 18 is provided at its rear cross-bar with a collar to receive the vertical pipe or tube 1, and upright bars 21 and 22 are secured at their lower terminals to the rectangular frame 18 and rise therefrom. The upper ends of the bars 21 and 22 are threaded and extend through eyes or perforations 23 of the cross-bar 17. The cross-bar 17 is secured at one end to the upright bar 22 by a nut-24, and the threaded upper end of the other bar 21 receives a guide 25, having a vertical slot or opening and provided at its lower end with a threaded perforation to receive the bar 21.

The guide extends upward from one end of the top cross-bar to receive a lever 26, which is adjustably connected to the upper portion of the valve-stem 5. The top cross-bar 17 is provided with a pair of upwardly-extending cars 27 to receive the inner end of the lever 26,which is fulcrumed on a suitable pivot passing through perforations of the ears 27. The lever is provided adjacent to its pivoted end with a perforation or opening for the valvestem, and it carries a set-screw 28 for engaging the same. By this adjustment the opening of the valve may be readily controlled. The valve 6 is normally maintained in engagement with its seat by means of a coiled spring 29, disposed on the valve-stem and interposed between the upper guide 3 and a suitable stop 3() of the valve-stem. The stop 30 preferably consists of a collar adjustably secured to the valve-stem by a set-screw. When the lever is swung downward, the valve 6 will be opened and water will be permitted to flow upward through the vertical pipe or tube, which is provided at its upper portion with a discharge pipe or nozzle 31, arranged at an inclination, as shown in Fig. 4.

The outer end of the lever 26 is connected by a rod 32 with an arm 33 of a rock-shaft 34, which is also provided with a depending arm 35, the arms 33 and 35 being located at one end of the shaft 34 and being arranged at approximately right angles to each other and forming a bell-crank lever. The shaft 34 is journaled in suitable bearings 36 of the rectangular frame 18, and it forms a pivot or fulcrum for the bell-crank lever. The arm 35 is connected, by the means hereinafter described, with a depressible platform 37 adapted, as hereinafter explained, to be actuated by the weight of an animal, whereby the bellcrank lever will be oscillated and will swing the lever 26 downward and open the valve.

The valve is retained in its open position until a predetermined quantity of water is obtained by means of an oscillatory weighted bucket-supporting frame 38, consisting of an approximately U-shaped body portion and a rearwardly-extending stem 39. The U-shaped body portion is pivoted at opposite sides to the upright bars 21 and 22, and a bucket 40 is pivoted between the sides of the body portion of the weighted frame at the front end thereof. The bucket is located beneath the spout or discharge 31 in position to receive water flowing therefrom, and the rod 39 receives an adjustable weight 41, which overbalances the bucket and which is adapted to swing the same upward when the oscillatory bucket-receiving frame is free to move and the bucket is empty. The pivot 42, which extends through the bar 21 and which supports the adjacent sides of the oscillatory bucket-carrying frame, has rigidly connected to it a depending arm 43, located on the exterior of the bar 21 and havinga lower bifurcated end 44, arranged in the path of the arm 33 of the bell-crank lever. The pivots of the bucket-carrying frame are supported by suitable braces 45, and the bifurcated end 44 receives a roller 46, which normally engages the outer or rear end of the arm 33. When the platform is depressed by the weight of an animal, the arm 33 is swung downward, as

hereinafter explained, thereby swinging the lever 26 downward and opening the valve. As soon as the arm 33 moves downward to a point below the engaging member or roller of the arm 43 the latter swings forward and the roller lies directly above the rear end of the arm 33 and prevents the valve from closing. The roller provides a frictionless engaging element for the arm 43; but any other suitable means maybe provided for this purpose. The arm 43 is swung forward by the weight 41, and its forward movement is limited by a projection 47, extending from the exterior of the arm 33. The weight 41 overbalanees the bucket, and as soon as the arm 33 is moved downward and the frame 38 is free to move the said weight lifts the bucket and maintains the same in an elevated position until suflicient water flows into the bucket and overbalances the weight. The downward movement of the bucket swings the arm 43 rearward, and the spring, which is connected with the valve stem or rod, closes the valve and raises the arm 33 to a position in front of-the roller 46.

The bucket is provided at its bottom with an opening 48, which is covered by a valve'49 when the bucket is elevated and which automatically uncovers the openingwhen the bucket descends to permit the water to flow into a tank or receptacle 50. The valve 49 is provided with a stem 51, extending upward and downward from the valve and supported by upper andlower guides 52 and 53. The upper guide is approximately inverted U-shaped and is provided with straight sides which receive eyes 54 of the valves. The straight sides are connected by a top piece which is provided with a central perforation or guide-opening for the upper portion of the valve-stem. The lower guide 53 is provided with a depending L-shaped arm which is provided with an opening to receive the lower portion of the valve-stem. When the bucket descends, the

IIO

lower end of the valve-stem strikes the bottom of the tank or receptacle, and thereby opens the valve, which remains in an open position until the bucket is again lifted by'the action of the weight 41.

The receptacle 50 is connected with the supporting-frame formed by the posts 19 and their connections by a hook 55, which enables the parts to be readily connected; but any other suitable means may be employed for this purpose. The tank or receptacle 50 may be of any desired construction, and it is connected with an inclined pipe or conduit 56, adapted to convey the water from the bucket to a watering trough 57. The wateringtrough, which is approximately semicircular or semi-oval in cross section, is pivotally mounted between a pair of upwardly-projecting bearing-arms or brackets 58, and it is normally maintained in a partially-inverted position, as illustrated in full lines in Fig. 1 of the accompanying drawings, to enable the water to drain from it after use, to prevent ice from collecting in it in cold weather, and also to insure a fresh supply for each animal. The watering-trough empties into a tank 59 and escapes therefrom to a suitable discharge-pipe 60. The tank is located within a frame 61 at the inner end thereof, and the platform 37 is mounted between the outer portion of the frame.

One of the pivots of the drinking-trough is provided with an upwardly-extending arm 62, provided with a series of perforations, and is adjustably connected to an inclined rod 63, which has its lower arm adjustably connected to an arm 64 of a transverse rock-shaft 65. The arm 64 is provided with a series of perforations, and the rod 63 is capable of adjustment to secure the proper movement of the Watering-trough. The transverse rock-shaft is provided with a central depending arm 66 and is connected by a rod 67 with a depending approximately U-shaped arm 68 of the platform, which is hinged at its inner end by a shaft or pintle 69. The platform, which in practice is designed to be located approximately level with the surface of the ground to facilitate its operation by an animal, is maintained normally in an elevated position by a pair of springs 70, secured at their outer ends to a shaft 71 and having their inner ends engaging the depressible platform. The shaft 71, which is journaled in suitable bearings of the platform-receiving frame, is provided at one end with an arm 72, adapted to be adjusted to vary the tension of the springs, and the said arm may be secured in its adjustment in any suitable manner. In the accompanying drawings the arm 72 is shown as resilient, and the adjacent side of the platform-frame is provided with a curved series of perforations adapted to be engaged by the arm 72, which has its outer end bent inward to provide an engaging portion. In order to enable the platform to move freely and frictionlessly,antifriction-rollers 74 are provided, and these rollers may be mounted either upon the lower face of the platform or upon the upper end of the springs, as will be readily understood. WV hen the rollers are mounted upon the lower face of the platform, the springs will be shaped to receive the rollers and slide thereon. The platform-receiving frame is designed in practice to be set into the ground and to be supported upon posts or stakes driven into the ground to provide a firm foundation or base.

When the platform is depressed, the transverse rock-shaft is rotated and the'arm 64 is oscillated to swing the drinking-trough downward from the position shown in full lines in Fig. 1 to that illustrated in Fig. 2

to arrange it for receiving the water. This movement of the transverse rock-shaft also operates to oscillate an arm 74*, located at the side opposite that at which the arm 64'is located and connected by a rod 75 with a lever 76, located within a casing 77 and fulcrumed at its upper end on the same. The lever 76 is arranged in upright position and is connected at its lower end to the said rod 75 and is provided between its ends with a-series of perforations to receive a pivot 78 for adjustably connecting a trip-dog 79 to it. The trip-dog 79, which is arranged approximately in a horizontal position, is pivoted at its rear end to the lever 76 and is provided at its front end, which is bifurcated, with an antifrictionroller 80. The trip-dog is provided between its ends with a depending lug or tube 81 and is guided by a keeper 82, secured to the easing and having a depending approximately L-shaped guiding portion. The lug or tube 81, which depends from the trip-dog, extends into a slot or opening 83 of a reciprocating rod or bar 84, which is mounted in suitable guides 85 and which is completely housed within the said casing 77. The guides 85 consist of posts having slots or openings to receive the bar 84 and provided with antifriction-rollers 86, mounted in the slots or openings and located beneath and supporting the bar 84. The front end of the trip-dog is supported upon an inclined trip 87, whereby when the dog is moved rearward, it will actuate the reciprocating bar during a portion of its movement and will be automatically lifted out of such engagement by the inclined trip to permit the reciprocating bar to return to its initial position before the depressible platform and to permit the valve to close as soon as the bucketreceives suflicient Water to oscillate the frame 38 and carry the depending arm 43 out of engagement with the arm 33 of the bell-crank lever. The inclined trip 87 is adjustable, being secured at its upper end by a set-screw 87 and provided at its lower end with engaging portions 88, adapted to interlock with any one of a series of notches 89 of the casing. The set-screw operates in a slot 90 of the casing and has its head arranged on the exterior thereof. The rear end of the reciprocating rod 84: is connected by a wire 91 or other suitable means with the depending arm 35 of the bell-crank lever. An antifriction-roller 92 is mounted in the slot or opening of the rod 8a to enable the lug or tooth of the trip-dog to readily disengage itself from the bar 84.

When the platform is depressed by the weight of an animal, the pivoted drinkingtrough is swung downward to an upright position to receive the water and the valve is opened and locked in such position before the reciprocating bar is released by the trip mechanism. As soon as the bucket receives a sufficient amount of water to overbalance the weight 41 it will oscillate the frame 38, thereby releasing the valve 6 and opening the valve 49. This shuts off the flow of water from the discharge pipe or tube 31 and permits the water from the bucket to flow through the pipe 56 to the trough. As soon as the animal steps from the depressible platform the latter is raised by the springs, which invert the trough and empty the water therefrom.

The lower end of the pipe 56 is supported by an arm 93, having a lower forked or bifurcated terminal to straddle the inner end piece of the platform-receiving frame and provided with an opening at its upper end to receive the pipe or conduit 56. The depending arm 66 of the transverse rock-shaft is provided with a series of perforations to receive the pintle ofthe connecting rod or bar 67, whereby the parts are adapted to be adjusted to permit the platform and the watering-trough to be positioned properly with re lation to each other. 7
